use of hyperlink in pentaho report designer 6.1

hello ,
Can anyone help me please in designing the report using hyperlink.
i wanted to popup a window on click of table row which redirects to another report. This i am achieving it using hyperlink and even i am passing the parameters. but i wanted to set the browser window size like we do in JavaScript.
window.open("http://www.w3schools.com", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=500,left=500,width=400,height=400");
And i wanted to know how to use system_parameters which are in hyperlink.
